Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2A02-TP is determined by the following critical electrical and mechanical parameters:

Voltage Rating: The substitute part must maintain a DC reverse voltage rating of 100 V or greater to ensure equivalent reverse bias protection.

Current Rating: The substitute part must support an average rectified current of 2 A or greater to handle the same load conditions.

Forward Voltage: The substitute part must not exceed 1 V forward voltage drop at the specified current to maintain circuit performance characteristics.

Recovery Speed: The substitute part must maintain standard recovery characteristics (>500ns, > 200mA) to preserve switching behavior.

Reverse Leakage: The substitute part must maintain reverse leakage current at or below 5 µA @ 100 V to ensure equivalent blocking characteristics.

Package Compatibility: The substitute part must use DO-15 or DO-204AC axial through-hole packaging to ensure mechanical fit and lead compatibility.

Operating Temperature Range: The substitute part must support the -55°C to 150°C junction temperature range.

Compliance: The substitute part must maintain ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

The 1N5392GHB0G from Taiwan Semiconductor Corporation is an active substitute for the obsolete 2A02-TP. Both components share identical voltage ratings, recovery speed characteristics, reverse leakage specifications, and operating temperature ranges. Both maintain ROHS3 compliance and MSL 1 ratings.

The 1N5392GHB0G carries AEC-Q101 automotive qualification, indicating compliance with automotive industry reliability standards. This qualification provides additional assurance for applications requiring enhanced quality and traceability documentation.

The primary electrical difference is the current rating: the 1N5392GHB0G is rated for 1.5 A average rectified current compared to the 2A02-TP's 2 A rating. Circuit designs operating at or below 1.5 A can directly substitute this part. Designs requiring the full 2 A capacity must evaluate alternative substitutes with higher current ratings or redesign to reduce current demand.

The forward voltage of the 1N5392GHB0G is 1.1 V @ 1.5 A, compared to 1 V @ 2 A for the 2A02-TP. This 0.1 V difference at reduced current levels has minimal impact on most circuit applications but should be evaluated in precision rectification circuits.

Both parts use identical DO-15 axial through-hole packaging, ensuring mechanical compatibility with existing PCB layouts and component placement equipment.

Frequently Asked Questions (FAQ)

Q: Can the 1N5392GHB0G directly replace the 2A02-TP in all applications?

A: Direct substitution is valid for circuits operating at 1.5 A or below. Circuits requiring the full 2 A capacity of the original part require evaluation of alternative substitutes with higher current ratings or circuit redesign.

Q: Are the DO-15 and DO-204AC packages physically identical?

A: Yes. DO-15 and DO-204AC refer to the same axial through-hole package format. Both designations are used interchangeably in industry documentation.

Q: What is the significance of the AEC-Q101 qualification on the 1N5392GHB0G?

A: AEC-Q101 is an automotive industry qualification standard. This certification indicates the part meets automotive reliability, quality, and traceability requirements. It does not restrict use in non-automotive applications.

Q: Does the lower capacitance of the 1N5392GHB0G (15pF vs 20pF) affect substitution?

A: Lower capacitance generally improves high-frequency performance. For standard rectification applications, this difference is not significant. High-frequency switching circuits should evaluate the impact on circuit behavior.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 2A02-TP and 1N5392GHB0G are ROHS3 compliant and carry MSL 1 (unlimited moisture sensitivity) ratings.

Q: What is the primary reason to substitute the 2A02-TP?

A: The 2A02-TP is classified as obsolete. The 1N5392GHB0G is an active product with current manufacturing and supply availability, making it suitable for new designs and legacy system support.

Q: How do the reverse leakage characteristics compare?

A: Both parts specify 5 µA @ 100 V reverse leakage current, ensuring equivalent blocking performance and leakage characteristics.

Q: Can the 1N5392GHB0G be used in circuits designed for 2 A operation?

A: No. The 1N5392GHB0G is rated for 1.5 A maximum average rectified current. Using it in 2 A circuits exceeds its rated capacity and may result in component failure or reduced reliability.
